iOS/Android: You probably know you can pinch to zoom in and out on Google Maps, but there's another, less intuitive shortcut that's more suited for one hand use.

All you need to do is double tap on the screen, then drag your finger up or down. Google will zoom in and out on the map as if you were pinching, but it's much easier to pull off with only one hand. This works on iOS and Android. Check out the video above for a quick demo.
